Abstract: Disclosed is a vehicle drawn device for cleaning a fence line. The fence cleaner includes a movable main frame with an attached rotating vertical tube broom which tube broom bristles come into contact with the fence line to remove dead and dried out vegetation which has become affixed to the fence line. The tube broom is capable of being tilted for better access to a fence line. Once the vegetation is removed from the fence line by the tube broom, the tube broom rotates the dead and dried out vegetation to a rotating clean off assembly. The clean off assembly extends parallel to the tube broom and contains a plurality of protruding teeth. The protruding teeth remove the dead and dried out vegetation from the rotating tube broom and force the vegetation into a chopper drum. A rotating horizontal feed accelerator continuously pushes the vegetation into the drum to avoid a buildup of vegetation. Upon entering the drum, a plurality of chopping blades cut the dead and dried out vegetation into small sections.

Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.
